This code won't run.. There is something wrong with "to_string"

#include <iostream>
using namespace std;
class Elevator
{
public: // Access specifier
int currentFloor; // Attribute (int variable) Current Floor number
bool upDirection; // Attribute (bool variable) flag for updirection
void move(int numFloors)
{ // Method/function to move between floors
if (upDirection == true)
{
currentFloor = currentFloor + numFloors;
}
else { currentFloor = currentFloor - numFloors; }
};
void stop() { // Method/function to stop
cout << "Elevator stoped" << endl;
};
string status()
{ // Method/function to move between floors
string str = to_string(currentFloor);
return str;
};
};
int main() { //Stack memory is set up by a simple variable declaration
Elevator stackObj; // Create an object of Elevator class and its stored in stack memory
// heap memory is set up through the use of the new keyword
Elevator* heapObj = new Elevator(); // Create an object of Elevator class and its stored in heap memory
cout << "Elevator move upward call using stack memory object " << endl;
stackObj.upDirection = true;

I added a header include string and the code worked. but the output is confusing... how to organize?

One problem I see is that currentFloor is not initialized so it has a random value.

It needs formatting for readability.

Please edit and add code tags.

Line 14: You have a typo. * instead of =.

You really should have a default constructor to initialize the state of currentFloor and upDirection.

Encapsulation dictates that currentFloor and upDirection should be private.
